Fish and Wildlife Investigates Dentist in Lion Killing

The U.S. Fish and Wildlife Service is investigating whether the killing of a beloved lion by an American dentist in Zimbabwe was part of a conspiracy to violate a U.S. law against illegal wildlife trading, a source close to the case told Reuters on Thursday.

The source said the service is investigating the killing under the Lacey Act, a U.S. law that bars trading in wildlife that has been illegally killed, transported or sold.

The investigation is focused on whether Walter Palmer, a dentist in suburban Minneapolis, was involved in a conspiracy to violate the act, the source said.

Separately, the Fish & Wildlife Service said it has been unable to contact Palmer. He has said he killed the lion, known as Cecil, but said he believed the hunt was legal.

Edward Grace, deputy chief of law enforcement for the service, issued a statement urging Palmer to contact the agency immediately.

The death of the famous lion has sparked international outrage. Protesters gathered outside Palmer's dental practice on Wednesday, calling for him to be extradited to Zimbabwe to face charges of taking part in an illegal hunt.

Fish and Wildlife Service director Dan Ashe in a post on Twitter on Thursday called the killing tragic and said his agency will "go where facts lead" in its investigation.

A Zimbabwean hunter has been charged in the African country with failing to prevent the unlawful killing of the lion.

Palmer has not been charged in Zimbabwe or the United States at this point.
